The balloon pic lighting is quite flat, except on your face where there are hard shadows. The pose is a little unadventurous, combined with the flat light, to make an impact, though it does show your figure.

Love the bum shots though the bath one shows everything in great detail o_o and could have been lit to bring out your sexy form without revealing quite so much... unless that's the intention, of course The bath pics do show lovely clear skin.
